Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-4320 in the wild and no public exploit code.\n\nAffected product: Atlassian Bitbucket Server before 4.7.1. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-4320/ (Markdown: https://insights.sbomify.com/CVE-2016-4320/index.md)","id":"CVE-2016-4320","markdown":"https://insights.sbomify.com/CVE-2016-4320/index.md","name":"CVE-2016-4320","record":{"aliases":["GHSA-mmfc-28m2-824q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Bitbucket Server","requires_auth":"low_privilege","summary":"Remote attackers can read the first line of arbitrary files via directory traversal in pull requests, requiring an upgrade to Bitbucket Server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"bitbucket","vendor":"atlassian"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Atlassian Bitbucket Server before 4.7.1 allows remote attackers to read the first line of an arbitrary file via a directory traversal attack on the pull requests resource.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path traversal in Atlassian Bitbucket Server before 4.7.1","id":"CVE-2016-4320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in n/a","id":"CVE-2016-4322"},"packages":[],"prev":{"headline":"Cross-site request forgery in Atlassian JIRA Server before 7.1.9","id":"CVE-2016-4319"},"products":["Atlassian Bitbucket Server before 4.7.1"],"published":"2017-04-10","related":[{"cvss_score":8.8,"headline":"Atlassian Bitbucket Server and Data Center Command Injection","id":"CVE-2022-36804","kev_date_added":"2022-09-30","published":"2022-08-25"},{"cvss_score":9.9,"headline":"Path traversal in Bitbucket Server","id":"CVE-2018-5225","kev_date_added":null,"published":"2018-03-22"},{"cvss_score":9.8,"headline":"Command injection in Bitbucket Data Center","id":"CVE-2022-43781","kev_date_added":null,"published":"2022-11-17"},{"cvss_score":9.8,"headline":"Command injection in Bitbucket Data Center","id":"CVE-2019-15000","kev_date_added":null,"published":"2019-09-19"},{"cvss_score":9.1,"headline":"Path traversal in Bitbucket Data Center","id":"CVE-2019-3397","kev_date_added":null,"published":"2019-06-03"},{"cvss_score":8.8,"headline":"Command injection in Bitbucket Data Center","id":"CVE-2019-15010","kev_date_added":null,"published":"2020-01-15"},{"cvss_score":8.8,"headline":"Path traversal in Bitbucket Data Center","id":"CVE-2019-15012","kev_date_added":null,"published":"2020-01-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can read the first line of arbitrary files via directory traversal in pull requests, requiring an upgrade to Bitbucket Server.","url":"https://insights.sbomify.com/CVE-2016-4320/"}
